AI in Vertical Farming and Greenhouses Quiz

Answers and explanations appear as you take the quiz.

1. What is the key difference between a greenhouse and an indoor vertical farm?
   • Greenhouses never use sensors
   • Vertical farms only grow fruit trees
   • Greenhouses use sunlight supplemented by artificial light, while vertical farms stack layers under LEDs in sealed buildings
   • Vertical farms rely entirely on rainfall
2. Which two variables together determine vapor pressure deficit (VPD)?
   • Humidity and temperature
   • Light spectrum and pH
   • CO2 and electrical conductivity
   • Photoperiod and nutrient flow
3. When does CO2 enrichment raise photosynthesis, according to the guide?
   • Always, regardless of conditions
   • Only at night
   • Only when nutrients are removed
   • Only if light and temperature allow it
4. Which institution runs the Autonomous Greenhouse Challenge?
   • John Deere
   • Wageningen University & Research
   • AeroFarms
   • The PCAOB
5. What core economic problem does the guide identify behind vertical farm failures?
   • They replace free sunlight with purchased electricity while selling low-priced crops like leafy greens
   • They grow too many high-value crops
   • They have no capital costs
   • They use too little electricity
6. Why is reinforcement learning hard to apply directly in greenhouses?
   • Plants cannot be measured by sensors
   • Algorithms are banned in agriculture
   • Growth cycles take weeks and mistakes can cost a crop, so experiments are slow and risky
   • Greenhouses have no historical data
7. How is model predictive control used in greenhouse AI?
   • To randomly change settings each hour
   • To replace all sensors with cameras
   • To shut off climate control completely
   • To plan setpoints hours ahead using weather forecasts and electricity prices
8. Are vertical farms automatically more environmentally friendly, according to the guide?
   • Yes, always
   • No, their carbon footprint depends on the electricity source
   • Yes, because they use no energy
   • No, because they cannot grow any food
